Does natural gas release carbon dioxide when burned?

Answer 1

Yes, it does. Natural gas is methane, a fossil fuel greenhouse gas 21 times more powerful than carbon dioxide. So when it escapes into the atmosphere it is very damaging. And when it is burnt it emits carbon dioxide, another greenhouse gas.

Answer 2

Yes, burning petroleum releases carbon dioxide, which adds to the greenhouse gases in the atmosphere.

Carbon was stored in oil many millions of years ago. Releasing it now by burning for transport and electricity is adding huge amounts of CO2 that were safely stored away.

Answer 3

Natural gas as a fuel is made of molecules that contain carbon and hydrogen (hydrocarbons). The simplest is methane CH4.

When gas is used as a fuel it is used in a chemical reaction which unites the carbon atoms and the hydrogen atoms with oxygen atoms from the air, and this releases chemical energy as heat that is used to boil water to make steam for driving turbines to generate electricity. The byproducts are carbon dioxide CO2 and water H2O in large quantities.

Most of the heat comes from the formation of the carbon-oxygen bonds to make CO2. Because oxygen is a heavier atom than carbon or hydrogen, the mass of CO2 produced by burning 1 kg of fuel is 2.5-3.5 kg, depending on the precise chemical composition of the fuel.

CO2 can be separated out again into carbon and oxygen by the action of sunlight on vegetation, call photosynthesis. The quantities of CO2 being formed in power plants is beyond the power of the Earth's vegetation to process at present, therefore the amount of CO2 is increasing.

Answer 4

No. Natural gas itself is mostly methane.Burning methane releases carbon dioxide

Answer 5

Yes, it does.

Answer 6

Yes, burning natural gas produces carbon dioxide (CO2) as a byproduct. This greenhouse gas contributes to climate change when released into the atmosphere.
